General Information: A medium carbon steel for quench and tempering steel with high hardenability. Ovako 477L has high tensile strength in combination with high toughness, and it is often used for large axles and machine parts. By using air– or gas-quenching it is possible to reduce the amount of quenching distortion. Additionally the use of quenching medias such as oil and salt may be avoided, which improves both safety and environment. The sulphur content is in a low and narrow range for consistent machinability. Suitable for nitriding Suitable for induction or flame hardening Through hardenability corresponding to a bar with approx 60mm diameter (cooling in still air) Provides low distortion Weldable under certain conditionsInformation provided by Ovako |
